Abstract [en]

TrustZone is an extension of the ARM architecture that allows software executed in ARM processors to be split in two environments: the normal world that runs a common operating system (e.g., Android or Linux) and its applications, and the secure world that runs security services or others that need to be isolated from the normal world. This work aims to provide support for analyzing the security status of the normal world from the secure world. For this purpose, we present a Virtual Machine Introspection (VMI) library that leverages the TrustZone architecture. VMI tools and the library run in the secure world and inspect the normal world. We present an experimental evaluation of the library in an i.MX53 development board.
